A positive Sm/RNP Ab result indicates the presence of antibodies reactive with the Smith (Sm) protein and/or ribonuclear protein (RNP). This Sm/RNP assay cannot distinguish between Anti-Sm and Anti-RNP activity, thus should be considered with the Sm Ab test result to determine clinical significance.
